Abstract- This paper introduces a new method of
secured voting system. The conventional voting
mechanism follows the issue of voter id and other details
which is generated manually. So, there are chances of
parallax errors. To avoid this, automation had been
developed. The details of the voters are extracted from
aadhar card database. OTP (One Time Password) will be
sent to the persons through their mobile phones to enter in
the keypad. At the time of voting fingerprint
authentication and OTP is required for the voter. When
people cast their vote the results will be updated
automatically in IOT (Internet of Things). As soon as they
cast their vote, their voter id and other details will be
erased automatically and the aadhar card details which
they used will be tracked and will be locked to access
again. Results will also be published on the same day of
election.
Keywords- IOT, Fingerprint, OTP, Aadhar card,
keypad.
1. INTRODUCTION
Voting is the freedom of the people in a democratic
country. The current voting system is called as Electronic
voting system. It uses electronic ballot to store votes.
Sometimes fake display units can be installed in order to
show manipulated numbers but fake votes will be
generated in the backend. Such fake display units are
commonly available in the market so there will not be a
need for hacker to hack the device. The people who are
in powerful government position can do this within
overnight with their money and powers they possess.
Then what about democracy? What about people’s who
vote? The Democracy principles depend upon the
people's decision. So, to have great vision we need to
take correct decision. This can be made by "voting". The
conventional voting mechanism follows the issue of
voter id and other details which is generated manually. It
leads to many manual errors. Moreover the electronic
voting machine may be devised in a such a way that
people whomever they vote, will be converted into some
other's party or candidates. It may be misused in many
ways. Electronic voting is the usual way of voting. E-
voting (Electronic Voting) is one in which a
representative supervises when the person castes
his/her vote. I-voting (Internet Voting) is one in which
the voter votes from home with the help of the internet.
2. OVERVIEW
The details of the persons who are above 18 years are
extracted from aadhar card database.OTP will be sent to
the persons mobile phones. At the time of voting, the
user can give their fingerprint authentication and specify
OTP in keypad. Once the voter casts the vote, the vote
gets stored in the server which is made possible using
the IOT. By this way we can avoid fake votes and
multiple votes casted by the same voter. The server gets
update automatically after each vote is casted. So by the
end of the voting process we can directly get the results
from the server and announce the results on the same
day.
2.1. Hardware architecture
In our proposed model we make use of the PIC controller
for processing data and fingerprint sensor to detect the
fingerprints for authentication and security. It takes the
fingerprint access from the voter to allow the person to
cast the vote. It also consists of a power supply, LCD
display, Buzzer, Keypad, UART and mobile phone as the
receiver unit.
2.2. IOT technology
For this voting system we use the IOT technology to
store the votes. A server is created and the votes are
stored and updated automatically. By doing this the
results of the election can be announced on the same day
which is much easier than the counting process.
2.3 Working
The power supply acts as the source for the kit. The
buzzer is used to acknowledge once the voter has casted
the vote successfully and also to alert when a user has
voted multiple times. The keypad is used to enter the
OTP which has been sent to the mobile unit which is
registered already in the aadhar card. The voting unit is
used to cast the vote to the preferred party and the LCD
display is used to display the name of the party for which
the voter has voted. All the information and details are
stored and updated into IOT. So at the end of the voting,
results can be published immediately by retrieving the
data from cloud server.

2.4 Implementation
Initially the power supply is switched on to start the
process. A step down transformer is used to convert AC
high to AC low voltage and current. The bridge rectifier is
used to convert the AC to DC. In order to reduce the
noise present in the DC signal the capacitor is used to
filter it. The circuit requires only 1A and 12v supply. The
PIC microcontroller has 40 pins out of which 32 pins are
used for I/O operations (Input and output). Port A is
connected to the fingerprint sensor, Port B is connected
to the keypad, Port C is connected to the Buzzer and the
Port D is connected to the LCD display respectively. Then
sim card is inserted in the IOT. Now the fingerprints are
registered using the sensor and once the fingerprint is
verified with the aadhar card database, an OTP is sent to
the receiver unit. This OTP is entered in the keypad. If
the entered OTP is correct the vote can be casted by
selecting the party else the LCD display shows wrong
OTP and the buzzer also notifies the wrong OTP entered.
The votes casted by the candidates are stored in the
server through IOT cloud.

3. Conclusion
The proposed system consists of a few additional
components in order to improve the security and also to
provide authentication. This paper tells about the new
way of voting system. This kit can be further minimized
to small size with more advanced technologies. This
eliminates difficulties faced due to the fake voting and
reduces the vote counting time since IOT technology is
used. In future, I-Voting can also be changed with these
security measures where face recognition can be used
instead of fingerprint biometric. It reduces the queue
standing for voting since everyone can vote from their
house itself.
